for some reason, the scrollwheel on my laptop doesn't work. well, it works, but it doesnt. let me explain: when I scroll in any program, nothing happens. however, my mouse pointer still changes to the one with the scrollwheel next to it (it usually changes to that while i'm scrolling) so I know it detects my scrolling. I tried updating my mouse drivers to the most recent one, but the installer told me that I already had the most recent ones. I looked on some random site that suggested changing firefox settings for some reason, didnt work either. I don't know what to do!
